senn No. 163,007. (No model.)

adapted to engage the adjacent spiral groove 27 or 30, while'the other end of each of said blocks projects through plate 34: and is provided with beveled ends, as clearly shown in Fig. 1. The two plates 32 and 33 are locked together by suitable clutch members 36, which prevent relative angular movement, but permit relative axial movement, and the plate 33 in the construction shown is held against angular movement by a bracket 37 It is to be understood that this is only a means of holding the parts 32 and 33 and 26 and 29 from revolving together and that other means may and in many cases will be employed for the purpose without departing from my invention.

Wound about the hub of plate 32 is a compact volute spring 38, each end of which is attached to plate 32, thus forming a series of substantially concentric laminae, which form a contact member, the inner face of which is beveled, as at 39, to conform to the angle of the adjacent face of wheel 25 and the inner edges of whichlaminae are arranged to be engaged by the sliding blocks 35. Similarly there is wound about the hub of plate 33 a compact volute spring 40, the inner face 4:1 of which is similarly beveled.

Disk 29 is provided with a suitable handwheel 29, by means of which it, and consequently disk 26, may be rotated with relation to plates 32 and 33.

It is desirable that the laminae of the structures 38 and 40 shall be kept from movement" relatively toeach other, or. in other words,

thatin the fclock-spring form shown they shall not be permitted to wind up tightly enough to prevent their free sidewise move mentwhen operated by the blocks 35. Itherefore form transverse cuts therein, one or more, 9

(two being shown,) and form upon the adjacen surfaces of the platespcorresponding ribs 1', which will .enter the grooves formed by said cuts, thus holding the laminae against any possible circumferential relative movement. These ribs'are indicated by dotted lines in Fig. 2, and one of them is shown in section in Fig. 4,. The operation is as follows: The two volutes 38 and 40 need to bekept from revolving with the disks 26 and 29' and in the construction shown are held stationary by means of bracket tionary. member and a planetary member, a 37, so thatarotatien of easing l9about shaft volnte spring; forming the operative face of 10 causes a planetaryinoveinent of the whee s one ofsaid members;- a series er blocks ar- 25 25, and these wheels are engaged between ranged behind said spring, and means for adopposite rings which are formed by projected justing said blocks radially with relation to 7 laminae of the volutes 38 and 40, said. laminae said spring, whereby successive portions of being projected by ,blocks 35, a By turning saidspring at differentdistances from the axis disks 29 and 26 upon shaft the blocks 35 thereof may be projected into operative enmay be shifted radially, and thus change the 'gagement with the other member.
